After cleaning the throttle, the engine can't return to idle immediately after starting!

Almost all EFI gasoline vehicles generally have a high idle speed after cleaning the throttle, because ECU will record and form a fault code when removing the throttle position sensor, which cannot be cleared after power failure (except for a few models), and the fault code must be cleared by decoder. If the fault code cannot be eliminated after clearing, the problem must be solved by idle speed matching decoder. Precautions during matching: Before continuing operation, run the engine to normal operating temperature (95 degrees).
